The Filmmaker perhaps.. But the people in the film say what they say.. they are scientists and therefore a consensus does not exist ..

Well there were a lot of contributors, not all of them scientists from a relevant field, some of them misrepresented, some of them not actually expressing their stance on climate change data itself, but more disapproving of the IPCC's approach to the issue.

One of the contributors, for example, has postulated that the international hand-wringing over climate change is actually a sour-grapes assault on African development. This contributor, James Shikwati, is an economist and author.

Among the other contributors are former British minister Nigel Lawson, weather forecaster Piers Corbyn, and author Paul Driessen who is a lobbyist and wrote books on "eco-imperialism".

Besides which even if all contributors were honestly represented in the film, 20 voices among thousands is not disrupting a consensus.
